Um estudo sobre o ensino de matrizes no nível médio da educação básica

Abstract

The present work has as its theme the teaching of Matrices content in High School, and its choice was due to its relevance for understanding fundamental concepts in Mathematics and its applicability in different areas. Our central objective was to analyze the teaching strategies for the content of Matrices in High School, of a Mathematics teacher from the public school in which we carried out our Supervised Teaching Internship IV, where we sought to identify the challenges faced by students in understanding the content. For the study, we made some mentions of articles related to the teaching of Matrices, as well as an analysis of the content of matrices in Brazilian curricula, specifically the National Common Curricular Base BNCC, in addition to indicating a digital resource as an aid in Problem Solving. Although we did not intend to discuss learning the content, we also raised students' difficulties in resolving five questions involving matrices of an assessment applied by the teacher. In this data collection we tried to survey the number of correct answers, and we sought to identify the possible resolution strategies for each issue analyzed. The results revealed high rates of errors in answering the assessment questions, indicating students' difficulties in the content. The mistakes made point to the need to review the teaching strategies observed and propose activities that encourage the practical application of elements studied in Matrices, aiming to improve students' understanding and performance.
